Liubangcun, Fusui (IVPP) (Cretaceous of China)

Also known as Luibang Quarry; Longcaoling quarry, Liubangcunxi

Where: Guangxi, China (22.6° N, 107.9° E: paleocoordinates 23.2° N, 116.1° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Xinlong Formation, Aptian (125.0 - 113.0 Ma)

• date is biostratigraphic, based on vertebrates; fossils from lower part of formation. Originally incorrectly listed as "Napan" Formation and previously considered as the Napai Formation, but now referred to the Xinlong Formation (see Mo et al. 2016)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; red mudstone and fine-grained, red sandstone

• described as "fresh water", not marine. "This indicates that the fossil site had experienced a prolonged dry period before the debris flow occurred and the dinosaurs were buried, compatible with the

•inferred environment and ecology, characterized by aridity...The underlying deposit is a lakeshore subfacies. It may have been submerged in the rainy season, and exposed to the surface in the low water season, so that mud cracks formed when the lake dried up for a long time. The fossil-bearing deposit was probably formed by a sudden flood carrying gravels, sand, mud, and scattered dinosaur bones."

• "red and red-purplish mudstones and sandstones, with a dark red basal conglomerate."

•"a succession of purple-red sandy gravels, fine sandstones, muddy sandstones and sandy mudstones. The layer of sandy gravels has a thickness of 15–60 cm in the northern part of the quarry (where LCL 63 was discovered), while it becomes thinner and finally disappears southward. The underlying deposit exhibits a succession of purple-red, light-green mudstones, siltstones and fine-grained sandstones containing some calcareous concretions. The surface of this layer in the southern area is full of mud cracks. Some mud cracks are nearly 30 cm in depth and 8 cm in width."

Size classes: macrofossils, mesofossils

Collected by NHMG, BRLF in 1960s, 1973, 2001, 2016–2016; reposited in the IVPP

Collection methods: mechanical,

• Fusuisaurus supposedly from same site as earlier discoveries made by local farmers (materials now lost)
